Istio is an open source service mesh that simplifies observability, traffic management, security, and policy. It extends Kubernetes to establish a programmable, application-aware network using the Envoy service proxy. 

Istio 1.12 was recently launched with an improved experience with WebAssembly that allows users to dynamically load custom-built extensions at runtime through an API.

The latest version also includes expanded support for configuring metrics and access logging to the API.  Istio 1.12 features a number of improvements to our Helm installation support including an official Helm repository and a new refined gateway chart. 

Istio has added full support for the ‘v1alpha2’ release of the Kubernetes Gateway API. This improvement aims to unify the diverse set of APIs used by Istio, Kubernetes ‘Ingress’, and other proxies, to define a powerful, extensible API to configure traffic routing.

Additional details on all of the latest improvements to version 1.12 are available here.
